I dont think i was suggesting that. Merely stating a hypothesis:
That if me remembers correctly, the only time zeroing the netstats is
considered valid is when you also change the ifindex as well i.e
it becomes a new device. Now i could be wrong. Someone more knowledgable
on SNMP needs to make the qualification.
